This lecture covers the study of ballistic motion in an accelerated frame of reference, focusing on the definition of inertial forces, Coriolis force, and the impact of Earth's rotation on the Foucault pendulum. It also delves into the equations of motion in a rotating frame and the implications of Coriolis force on cyclone rotation. Examples of a pendulum in a rotating plane and the application of Kepler's laws to central motion are discussed, along with the concepts of moment of inertia and center of mass.
